Is it on the engine? Valve cover gasket defective/leaking? We have some information about symptoms, repair, and costs, too. But first some general details. The cylinder head cover/valve cover is the upper part of the combustion engine. The cylinder head is closed. Job related task valve cover gasket It is to keep combustion gases and lubricants from escaping into the environment when the engine is running. So the valve cover is sealed with the valve cover gasket. It is usually made of plastic or rubber. However, it can be affected by age wear or tear They become leaky (brittle, hard, porous). Then the engine oil leaked!
Recognize wear and tear in time
Defective valve cover gasket is indicated in the above Oil leak Marked in the cylinder head area. This is especially evident in the area around the spark plugs, which then have a certain “oil moisture” at the top. It becomes clearer with one dripping, which can also be seen under the car after some time. If the leakage reaches a certain limit, this is indicated by increased oil consumption and visual warnings Oil pressure warning light (If there is a large loss of oil) Noticeable. However, there can also be other reasons for oil loss, such as defective reason Variable camshaft adjustment or defective camshaft oil seal to be responsible. The undisputed loss of oil represents a significant deficiency in the functionality of the car. However, as long as this is only brilliantly indicated”oil sweating“Not by a behavior Expresses no reason not to pass the main examination.
Troubleshooting/Replacing the defective seal
In short, the valve cover gasket fails to work exchange The only solution. One Repair straight a splatter I can not. The procedure is as follows. If available: reduction engine cover, after which the ignition coils and ignition cables are dismantled for better access to the valve cover. Depending on the model, the workload can be increased by disassembling intake manifolduntil expand by injection (It can happen from time to time) extension. Although the last step is the exception, it increases the voltage several times. The defective seal is now located between the cylinder head and the valve cover, which can be removed from its position and disposed of.
Depending on the age and pressure of the seal, after it is loosened, it is removed remains it is necessary. This, in turn, may be time consuming, but is essential for subsequent proper functioning. Once this happens, after the new seal is attached, the valve cover can be put back in and using the instructions provided by the manufacturer Tension values are attached to the cylinder head. If you allow yourself to be tempted not to replace the seal and instead try to eliminate the problem by “tightening” the cap screws, you will notice the return of the oil loss after a short time. The already lost properties of the old gasket will not return after tensioning again. Small spacers are often included in the sealant to prevent cracking when tightening.
Time and material costs of repair!
Of course, the truth is that costs vary widely Workload, affected by the disassembly of components, restoration of the sealing surface, etc. In addition to the costs of materials found between 10€ and 80€ per stamp Amount, said working time is a big factor. usually will About 1-2 hours per cylinder bank scheduled. Resulting labor costs up to About 50€ to 300€, based on an hourly wage of 100 euros. After changing the seal, this should also happen Engine oil including filter will be exchanged. Any costs incurred due to contamination in the system are addressed here.
The following note is necessary: For safety reasons, tuningblog recommends all repair, inspection and maintenance work exclusive In a specialized workshop!

Of course that was far from that!
In this Tuning Blog category are guides and instructions for common vehicle defects/repairs and for mounting accessories/tuning parts. Our articles explain in a simple way common defects and their corresponding repairs, as well as explain how the first signs of a defect become noticeable. In most cases, we also have preliminary guides for repair instructions in our repair instructions approximate Pending repair costs are listed. The goal of our subcategoryAuto Repair Manual“It is to create a knowledge launch for the next visit to the workshop with the initial advice. This may save you from tedious troubleshooting and small things can be done directly on your own. The same of course applies to the installation of accessories / tuning of parts.
